Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the battery negative terminal to ensure safety.
  • Ensure the vehicle is on a flat surface and securely supported with jack stands if necessary.
2. Clear Diagnostic Codes
  • Use the OBD-II scanner to clear any existing trouble codes after repairs are made.
  • Reconnect the battery and start the engine to check if the light returns.
3. Replace Faulty Components
  • Ignition System (if misfiring is detected):

    • Remove spark plugs using a socket and ratchet.
    • Inspect and replace any faulty spark plugs with OEM parts, ensuring proper gap.
    • If ignition coils are faulty, remove the electrical connector and retaining bolts, then replace with new coils.
  • Fuel System (if pressure is low):

    • Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
    • Disconnect the fuel line at the fuel rail using a line wrench.
    • Replace the fuel filter if applicable, and inspect the fuel pump for proper operation.
  • Air Filter:

    • Open the air filter housing and remove the old air filter.
    • Install a new air filter, ensuring it is properly seated.
4. Recheck and Finalize
  • After replacing components, reconnect all electrical connectors.
  • Start the engine and let it idle while monitoring for any abnormal sounds or behavior.
  • Perform a test drive to ensure normal operation and verify the check engine light remains off.
